login details sharing protection for membership plugin to avoid abuse


I didn't find any documentation about this and would like to know if there's a build in protection within the membership plugin to avoid login details being shared...

Scenario: I have a "bad member" (: who decides to "share" his login details all over the net, does the p-lugin handle this kind of abuse?

Possible solutions would be IP detection, block acces when simultanous logins with emails sent to admin and user...do you have a solution for this?

Thanks in advance.
